Be it known that we, WILLIAM DENT PRIESTMAN and SAMUEL PR1ES'1MAN,Sl1l)jeciIS of the Queen of Great Britain and Ireland, of v5 Holderness Foundry, Hull, in the county of York, England, have invented new and useful Improvements in Motor-EnginesOperated by the Combustion of Liquid which patents have been granted in Great Brit- [0 ain Decemh'er2l, 1886, No. 16,779; in Germany June 8, 1887, No. 43,273; in France June 25, 1887, No;,184,43 6; in Belgium J uue 28, 1887, No. 57,833; in Norway July 2, 1887, No. 695 in Italy July 7, 18S7-, Vol. XLIV, No. 421,,(prolongation May 22, 1888, Vol.

in Portugal March 8, 1888,33. 1,223,) of which the following is a-specification. This invention relates to motor-engincs'opcrated by the combustion of liquid hydrocan hon mixed with air; and it consists inimproved uleans'for mixing the said fluids in regulated quantities and proportions and forheating the'inflammable vapor s'o produced before admission to the motor-cylinder or other combustion-chamber.- In order that our invention may be fully understood, we will-proceed to describe the 0 same with reference to the accompanying drawings, whereof Figure 1 represents, partly in longitudinal section, a hydrocarbomengine embodying our invention. Fig. 2 is a detail sectional view on a large scale of the'vap'orizer Hydrocarbon, (for- 270;) in Cape'Col'eny Julyl2, 1887,

and the valve mechanism for. supplying the fluid and liquid thereto in proportionately regulated quantities. Figs. 3 and 4iarc'crosssections of the valve (I seen in Fig. 2. Figs. 5 and'6 are detail views on a large 801118 of the valve mechanismcontrolling the' supply of fluid and liquid from the rcservoi r to the vaporizer or mixing apparatus. Figs. 7, 8, and

,9 are detail views one large scale illustrating the construction of a-burner or lamp for heal? ing the vapor inthe vapol'iz ingchamber.

The type of engine employed to illustrate our present improvements corresponds in many respects with that'dcscribed in the specification to Leltcrs Patent of the United States dated October'5,1886,No. 350,200. The present I specification is accordingly directed and, so far as may be, confined to the particular parts or appurtenances to which our improvements appertain. 1

For regulating the supply of air and liquid hydrocarbon from the reservoir a (contaiinng compressed airand petroleum or otherlliquid hydrocarbon) tot-he vaporizer or mixing apparatnsb,wc employ valve mechanism controlled by the, action of the governor 0, such valve .mcchanismbeing shown to an enlarged scale in Fig.2, which is a longitudinal mid-section of the device.

d is a cook or regulating-valve,connected 'with'the governor-spindle 'c','Fig. 1, by means of the lever d, and serving to control the air and hydrocarbon passagcse and 0. Each of the latter is provided with :2 c'hamberye, packed with cotton wool, or other suitable filtering material, through which the fluids arei'espect ively strained on their passage to the mixingnozzle 0.

' The valve d. is retained within itsseating and adjusted by means of 1320 screw-cap d, the latter bearing on a shoulder formed on the valvespindle d", and being secured in place by'the lock-nut d. The orifices through the granted to John Joseph Reveley Huiucs, and 6.0

Mind 4, which arecross'secti'ons of valvedtaken through-the .5 11orts. or orifices therein, whereby increased -facility for regulatingfthe flow of the fluids is; 'atfordcth; The valve-spindle d? is prolonged.

.the air and hydrocarbon supply pipes or passages c:e,leading from thepetroleum-reservoir a, Fig.1, to the vapor-making device 1),:

and also for controlling the corresponding passages,- a 0'3, to theyapor-heating lamp h, is marked g in- Fig. 1, and is shown to an. enlurged scale-in vertical section in Fig. .5 and in side elevation in Fig.6. It comprises a [our-way valve, g, arra'ngedin such a'nianner 0 in relationto the air and hydrocarbon pipes orpassages loading from the petroleum-reserrow that n one position of the valve air and oil are conveyed to the vapor-burning lamp -hthrough the pipes e e', b ut are shut oil from. 5 the vapor-making apparatus b. In another positionof the valve the supply of air and oil to the lamp -is.closed -andcommunication through the pipes c'e to the vaporizer bis opened. Ina third position of the valve the supply of air and oil is shut off. both to the;

-vapor-making apparatus and to the heating lamp. Escape from the petroleum-reservoir heingunder-the last-mentioned conditions prevented, pressure may be generated therein either by means of a smallhand-pump or by turningihe engine by hand-and so operating the pump,.which serves in regular working for supplying the petroleum-reservoir with compress'ctLair. The valve gis furnished with a lever or handwheel ,which works againstan indicator, showing the positions respective} y apv }ll'0p-l'i3.t5,'filSt, for generating-'pressnrein the. petroleun -reservoir; preliminary to starting the engine,(corresponding with the third -position above referred to;);secondly, for heatengine is started,(cbrresponding with the first to accelerate the'fluid of the liquid.

"In the specification to the aforesaid Letters Patent granted to John'Joseph Revelcy Homes," dated October 5, 1886, thereis described and illustrated a device for mixing liquid hydrocarbon with, air in the preparation of hydrocarbon vapor, sueh V means includiuga mining; nozzle in which two concentric tubes are employed for conveying the liquid and air, re-

sp'ectively, the extremity of thepassage forthe v latter beingso formed as to direct the gas obliquely forward against the stream'of liquid asit issues from the extremity of the iuclosed pipe conveying the same, the two streamsmeeting at an acnte anglc and the gasacting l Y 9 According to our improved construction of s vaporized or mixing'apparatus, we employ two nozzle-tubes, m and m, Fig. '2, connected. respectively, with the two passages'e-and e. The no'zzle-tube m is embraced or inclosedgsby the nozzle-tube-m,and the current of fluid from passage e,flowin'g through the annular space'betwcen tubes m aud'm, is defleetedinward-andimpinges from all sides on the current as to oppose'hri'd measurably-retard the flow" of the latter,- and thus effect-a more intimate mixing ofthe fluids: .AS illustrated in Fig.

is in the forin ofia .backwardly directed cone which" fits eoncentrically'iuto .a'eonieal recess in the end of the tube m,.but*s'o asto leave. a I

assistthe motion of the latter,'but rather to obstruct and retard it.. The current arriving through passage e has its own impelling force,

quired to impeLitQ By the use of a mixing-nozzle constructed as above'descri bed the liquid is more minutely subdivided and dispersed in the gaseous medium, the resultant vapor being more readily ignited and the combustion rendered more perfect.

In Fig. 1,1. represents the exhaust-pipe from cylinder '70, which enters the chamber! and connects with a coil therein. "The object 12 of this is to'heat the va'porin'said chamber'by means-'ofthe waste gases. 'We do not claim this mode ofheating .in itself, and, therefore a have not; shown theheating coih For heating the vapor contained in the and the current through passage e isuot rechamber 1, besides utilizing the. waste'gases vice (It, "Fig. 1) is represented to an enlarged scale in the vertical section, Fig. 7, side clevation, 'Fig. 8, and plan, Fig. 9. It comprises two tubes, at m, one inclosed within 5 the other and shaped and arranged substantially as described with reference to the mix in -nozzleillustraledin'Fi 2, these two tubes being supplied from the petrolcuiii-reservoir awith air and Iiquid-hydrocarbon, respect- ,ively, by means of the pipes e c, For convenience of manufacture, the straining-chambers e are placed on opposite sides of the de vice. The lamp is provided with a metal chimney, h, peribrated with holes h for" the admission of air, such chimney or tube acting not only as a wind-guard, but serving to'heat the vapor audproniote its combustion;

For convenience, we call the vessel a. the .petroleumreservoir, although it contains an aeriform fluid as well as aliquid, and it may contain any suitable liquid hydrocarbon.

We have employed 6" to represent throughout: the 4 straining-chanibers,- as these are all alike or may be alike.
